N2  - The structural characterization of a new quasi- undecahydrate of samarium(III) picrate is described. [ Sm ( pic )2(OH2)6]( pic ).43/4H2O is monoclinic, C 2/c, a 39.96(1), b 7.951(2), c 24.233(9) &#506;, &#946; 110.92(2)&#176;, Z = 8, temperature c.295 K; R was 0.047 for 5010 'observed' diffractometer reflections. Like the cations of Part I, the present has two picrate and six aqua ligands; although the general stereochemistry is similar, the picrate ligands are both clearly unidentate, unlike previous arrays wherein one behaves in a quasi- bidentate mode utilizing an ortho-nitro oxygen atom.
